There are two problems with the visualization.
1. Continous memory allocation
2. The rendering is done by the software (probably this will require a separate
bug report). Your laptop will suffering because of this. Since the rendering is
done by clementine, the cpu utilization of clementine hits the roof. In the
original build around > 6 months back, the rendering was probably done by the
driver. I'm pasting top output for FC30 build and the top output of the
opensuse clementine build. In the FC30 build, when I turn on the visualization,
it is 'X' that starts consuming a bit more CPU. In the opensuse build, the
utilization of 'X' doesn't change at all, but CPU utilization of clementine
shoots up.
